Looking to make the plunge and add digital playback to my main system. I have heard good things about the Sony, however I already have an excellent DAC (McIntosh)so the Dac in the Sony is redundant. Also, I am not sure the sound quality from the Sony would be as good as the Aurender. I plan to play FLAC files from my NAS into the Aurender or Sony into my DAC. The price of the Aurender w/ 2TB drive is about US$600 more than the Sony. Not chump change, but may be worth the bucks in my opinion. Any suggestions or advice?
